I want the Steelers at home going for me in this spot. Pittsburgh laid an egg at New England on national television this past Sunday night. Ben Roethlisberger has a strong history of playing much better at home. The Steelers' offensive line is elite. James Connor and JuJu Smith-Schuster are more than adequate replacements from the departed Le'Veon Bell and prima donna Antonio Brown. 
Seattle is down this season. The Seahawks were life and death to beat a bad Bengals team at home opening week. Seattle is 3-6 SU and 0-8-1 ATS in the first two weeks of the season during the past four plus years. 
The Seahawks are down because they no longer have their fabled Legion of Boom secondary. All of those guys are gone. Their best defensive lineman, Jarran Reed, is suspended. 
Seattle is a ground-and-pound team. That style isn't going to work on the road against the Steelers, who won't lack motivation after last Sunday's humiliation to the Patriots. Pittsburgh ranked sixth in run defense and were tied for first in sacks last season. Russell Wilson lost his top wide receiver with Doug Baldwin retiring.
